I do not claim to be Yoda, Adolf Zukor, Louis Mayer, Carl Laemmle, Allen Koenigsberg, a Genius nor God. I am merely recently retired fellow that has an interest and desire to grasp the concept of, on, about The Sociology of Broadcast Music via Radio. And, I thank Frank for his patience and informative answers to my suppositions and the rest of you guys, too! Thanks. I am certain Mel Brooks could and should write a film feature script out of all of this hi-jinks presented here-to-fore. I do get a chuckle…..really I do….<grins>.
The definition of sociology is "the study of the development, structure, and functioning of human society."
Music is a product of human endeavor, but it has no sociology of its own as it is inorganic.
What I think you mean, in simpler terms, is the dynamic of the selection and programming of music on the radio.
And at the same time, I want to ask if English is your second language?
